Q. Electric power is transmitted over long distances through conducting wires at high voltage because
A) High voltage travels faster
B) Power loss is large
C) Power loss is less
D) Generator produce electrical energy at a very high voltage
Explanation
(c) Power loss in transmission$\ P_{L} = \frac{P^{2}R}{V^{2}} \Rightarrow P_{L} \propto \frac{1}{V^{2}}$
